When i press the button, facebook default login activity opens. When i press back, it goes back to the activity. I can try to login again, but when i switch orientation to landscape and go back, application crashes with this bug

I have digged dipper, and it seems that after u go back, LoginActivity - onResume is called and that calls AuthorizationClient method
void startOrContinueAuth(AuthorizationRequest request) {
if (appEventsLogger == null || appEventsLogger.getApplicationId() != request.getApplicationId()) {
appEventsLogger = AppEventsLogger.newLogger(context, request.getApplicationId());
}
if (getInProgress()) {
continueAuth();
} else {
authorize(request);
}
}
This method gets request = null, and ofcourse application cannot continue. Now i ve read that this bug should of been fixed, but it isnt. So i wonder are there any solution to this, i cant even force this loginACtivity to be portrait mode, since its orientation still switches. I am using facebook SDK 3.5.2
Thank you for your help
I have just tried this developers.facebook.com/docs/android It seems it fixes the issue, the login activity is now locked in portrait mode and when u come back the crash doesnt happen :)
